WALL BOARD JOINT Filed March 14, 1950 ymzz Patented Nov. 29, 1932 PATENTOFFICE DAVID MCOHESNEY, OF KIRKLAND LAKE, TIMISKAMING, ONTARIO, CANADAWALL-BOARD JOINT Application filed March 14, 1930. Serial No. 435,901.

My invention relates to improvements in wall board joints, and theobject of the invention is to devise a strong joint between the meetingedges of the boards which will 5 provide a surface over the jointsperfectly flush with the outer face of the board, and which willtherefore, not be visible through any surface finish such as paint orpaper applied to the face of the boards, and it con- 0 sists essentiallyof the arrangement and construction of parts hereinafter moreparticularly explained.

Fig. 1 is a perspective View of a fragmentary portion of a wall boardconstruction showing my joint applied thereto.

Fig. 2 is a sectional view taken transversely of the joint.

In the drawing like letters of reference indicate corresponding parts ineach figure.

1 indicates a portion of the frame of a building to which the wallboards are applied. 2, 3, 4 and 5 are the corner portions of a pluralityof wall boards applied to the frame with their meeting edges abutting.Each of the wall boards is provided with an edge depression or recess 6forming vertical or horizontal channels when the boards are assembled.

7 are metallic strips preferably formed of sheet metal which fit thechannels formed by the recesses 6 being secured in place by nails 8 and9 extending through perforations formed therein in proximity to theiredges and through those portions of the wall boards forming the base ofthe recesses 6 into the frame 1. v

The strips 7 are counter sunk beneath the surface of the wall board asclearly indicated in Fig. 2, and the channel formed by the recesses 6 isthen filled with a suitable plastic filling such as gyproc filling so asto produce a surface over the joint which is flush with the face of thewall board.

When the joint is finished as above described it will be readily seenthat a continuous smooth surface is provided through which the jointwill not be visible and will thereby permit of the face of the wallboard being painted or papered without the surface being in any waymarred by any slight having edge recesses forming a groove, a

metallic plate countersunk in the groove, securing nails extendingthrough the plate adjacent each edge thereof and through the adjacentedges of the wall boards, and a. filling for the groove flush with theouter face of the wall board.
